Preconception Testing in Boca Raton, Aventura & Palm Beach

Assessing Your Risk for Inheritable Genetic Diseases

Our mission at Palm Beach Fertility Center involves making every effort to help you get pregnant and have a healthy baby. Advanced reproductive technology and genetic testing give us the ability to identify barriers and pave the way for successful conception. One of these valuable tools we use is preconception carrier testing, which provides a clear picture of the risks for passing along inheritable genetic diseases.

Who Needs Preconception Testing?

As both a scientist and a father himself, Dr. Mark Denker recommends preconception genetic testing for any couple preparing to start a family. The relatively inexpensive test involves a blood or saliva sample and provides comprehensive conclusions about what is contained in your DNA. You can learn your carrier status for over 100 inheritable diseases.

Recessive Genetic Disease

A recessive genetic disease occurs when both copies of a particular gene have pathogenic variants. If you have one copy of a gene with a variant and one normal copy of that same gene, you are considered a "carrier" for that recessive genetic disease even though you are not affected by that disease.

In order for carriers to pass on a recessive gene, both partners would have to be carriers of the same genetic disease.

Dominant Genetic Disease

A dominant genetic disease occurs when one of the two copies of a particular gene has a pathogenic variant. Only one of the copies of the gene needs to have a pathogenic variant in order for an individual to be affected by a dominant genetic disease (recessive diseases require both copies to have variants). If either you or your partner have a dominant genetic disease, you run a 50% risk of having a child affected by that genetic disease.

X-Linked Disorders

The X and Y chromosomes (often called the sex chromosomes) determine whether a baby is male or female. Males have one X and one Y, while females have two X chromosomes. Some disorders are caused by variants or alterations of the X chromosome. Generally, if a woman has a pathogenic variant on one of the genes located on an X chromosome, she is considered a carrier — and has a 50% chance of passing that variant onto her children. If she passes on the variant on to a male child, that child can be affected with the condition. Affected males will not pass the variant onto their sons, but daughters of affected males will be carriers of the variant. Female carriers rarely develop symptoms of the condition but their daughters have a 50% chance of being carriers.

Testing for Specific Genetic Diseases

While anyone can benefit from genetic testing, certain situations necessitate it. For example, cystic fibrosis affects white and Ashkenazi Jewish couples. Black couples are at risk for having babies with sickle cell disease, and Jewish women of European descent are susceptible to passing on Tay-Sachs disease. Anyone with family ties to the Mediterranean, Africa, or Far East Asia will benefit from preconception genetic testing.

We will likely recommend preconception carrier testing when one or more of the following conditions are met:

  • You have a child with a genetic disease
  • You have a known family history for inheritable gene disorders
  • Your ethnicity or country of origin puts you at risk for genetic disease
  • You are a woman under 40 with an elevated follicle-stimulating hormone level

Fertility Treatment to Address Single Gene Disorders

If you have tested positive for a single gene disorder, we are here to explain the odds of passing along the recessive gene when you get pregnant. Both you and your partner will need to be tested to fully assess the risk. At Palm Beach Fertility Center, we offer targeted treatment to help you protect the next generation, as we want to ensure that you have a healthy pregnancy and give birth to a healthy baby.

Thanks to DNA mapping and advances in genetic testing, we have reduced the occurrence of inherited conditions by 90%.
